Object Oriented Programming
		• In the object-oriented programming paradigm, we begin to consider using classes in conjunction with one another. • We should no longer think about classes, or objects, in isolation from one another. • Instead of simply creating user defined data types, we create a hierarchy of related and interdependent classes and objects, following the natural structure of the problem. • This is because object-oriented programming extends the concept of data abstraction to apply across abstractions.
